artificial sand - what is it and how to make it | fote machinery
Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving.
In China, the artificial sand was mainly used in the construction of hydropower systems. For example, the Three Gorges Project and the Yellow River Xiaolangdi Project used artificial sand to prepare concrete. Due to the remote environment of the hydropower project and the high quality of sand and gravel, the projects have taken the materials locally.
Many Indian states have decreed the use of crushed sand in infrastructure construction because of its high compressive strength and cohesion and the adverse environmental effects of river sand mining, which will greatly boost the demand for artificial sand.
There are both natural and human factors in the increasing demand for artificial sand. The former is that the natural sand is about to run out, while human factors include people's requirements for environmental protection and the need for high-quality concrete.
With the development of infrastructure, the natural sand resources formed by hundreds of thousands of years in many countries and regions have been almost exhausted, which has affected the further development of construction projects.
Driven by huge interests, natural sand has been indiscriminately mining, which changes the river course, affects the safety of river embankments, destroys the living environment of fish and contaminates the groundwater. The crushed stone sand is an important alternative resource to change this phenomenon.
In the process of mining river sand, it often produces a large amount of tailings which is not used reasonably. Especially in small mines, the tailings are piled up at random, occupying land and polluting the environment.
Besides, in urban planning and construction, a large amount of construction waste is generated, which actually can be crushed by the crushers to produce the artificial sand and aggregates for promoting resource utilization.
With the rapid development of concrete technology, the comprehensive performance of high-performance concrete and high-strength structural concrete has higher requirements on the quality of aggregates, requiring it with stable quality, good gradation and shape, while less and less natural sand meets the requirements. Therefore, people are turning their focus on artificial sand.
Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete strength grade is below C60. When meeting the corresponding technical requirements, they can also be used for concrete projects such as ports and water conservancy.
The vibrating feeder feeds the stone evenly into the coarse crushing machines for the primary crushing of the stone. The crushed stone from the coarse crushing equipment is transported through the belt conveyor to the fine crushing machines for the secondary crushing.
The primary crushing equipment directly processes supplied materials from the stone material factory and is the foremost processing plant. The jaw crusher is the ideal choice for primary crushing.
The secondary crushing equipment is responsible for the middle and fine crushing in the stone crushing process. The secondary crushing equipment mainly includes impact crushers and cone crushers.
The crushed material is conveyed by the belt conveyor to the crushed sand making machine for fine crushing. The finely crushed material is then screened through the vibrating screen for coarse sand, medium sand, fine sand and other specifications.
VSI sand making machine is called high cost-effective sand making equipment with low initial investment cost and good use effect. It is high in operation efficiency with the PLST crushing cavity.
The HVI sand making machine manufactured by Fote is more advanced in technology. Its butt ends and lubrication scheme are modular in design, and the peripheral guard plate can be turned up and down to extend its life cycle. It has the effects of sand making and shaping at the same time.
For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the sand manufacturing machine, and the sewage discharged from the sand washing machine can be recycled by the fine sand recovery plant.
The following video shows clearly the difference between crushed sand and river sand from the aspects of source, wastage, setting time, shape, silt content and so on. It is worth collecting and sharing with friends.
The table below shows the mix ratio of M15 M55 and M55 M55 concrete designed for artificial sand and river sand. The results show that in the same Concrete Mix Design, the strength of concrete by artificial sand is higher.
As the demand for aggregates from China, Africa, Latin America, Europe,etc. will continue to rise, and the price of artificial sand will also increase, the outlook for the global aggregate market for sand and gravel is worth looking forward to.
According to the Global Sandstone Aggregate report, by 2020, the demand for aggregates of sand and gravel in the Asia-Pacific region will increase the fastest in the world, and the growth rate of India, Vietnam, Malaysia, Indonesia and other regions will be among the best.
Due to the economic transformation, the demand for sand and gravel aggregates in China will slow down. However, the report predicts that by 2020, China will still be the world's largest aggregate demander, accounting for almost half of the world's total aggregate.
The Global Sandstone Aggregate report shows that the reserves of natural sand are gradually decreasing globally, and in some developing countries where the demand for aggregates and sand is huge, illegal sand mining has happened frequently. According to the report, by 2020, the reserves of natural sand resources in some countries will be quickly depleted.
The depletion of natural sand resources will lead to a sharp increase in the price of aggregates and artificial sand, especially in areas where the demand for aggregates is huge. It can be seen that the profit margin of the artificial sand is very large.
The m sand manufacturing machine produced by the supplier Fote is suitable for m sand making production line of high hard and abrasion-resistant materials such as limestone, quartz stone, granite, river pebble, basalt, cement, various ores, glass raw materials, mechanism building stone, gold slag, etc.
The limestone, widely distributed in nature, is easy to obtain. It is the main raw material for manufacturing cement, lime and calcium carbide. After being processed, limestone is used in large quantities as building materials. Generally, simple processing process is through the limestone sand production line.
Quartz is a hard, wear-resistant, chemically stable silicate mineral mainly composed of silicon dioxide. It is an important industrial mineral raw material generally used in glass, building materials, ceramics, high-tech electronics industry, etc. after crushing and sand making.
The granite has the characteristics of hard texture, high strength, abrasion resistance and weathering resistance. It has the title of "The King of Rocks" and is a good building material. It is rich in resources with low mining costs but high product value. Granite is a popular choice when the product needs to be weather-resistant or durable.
The river pebble resources are rich with low collection costs and high application value. After making sand from river pebble, it is widely used in water conservancy and hydropower, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering and high-rise buildings in the engineering field.

how to fix the sand making machine?
For sand making machine, fixed work is only a part of its installation process, but it has a great impact on the use of equipment. If fixed work is not done well, the equipment may vibrate, or even break away from the foundation. For the process of work and the safety of staff, it is very unfavorable, so we should do a good job of fixing the equipment in the installation stage and the use stage. Here is to introduce how to do a good job of fixing the equipment.
First of all, the use of sand making machine is generally in a production line, rather than a single equipment working independently, so in order to do a good job in fixing the series of equipment, it is necessary to measure the size of the products purchased. Determine the size of each equipment, so as to make effective planning in the layout of production sites.
Secondly, when installing the sand machine production line, any kind of equipment should do a good job of fixing when installing. Mainly in its installation position to do a good job of cement grouting operation, and then install a fixed bolt on the corner position of the equipment, and fasten the bolt to ensure that the equipment is reliable.
This article mainly introduces the fixing work of sand making machine. Because the machine needs a lot of power when crushing materials, it must do a good job of fixing work when it is installed. The fixing work is analyzed in detail above. There are two main aspects: one is the measurement of the size of the equipment; the other is the measurement of the size of the equipment; the other is the measurement of the size of the equipment. It is grouting and bolt fixing during installation. Only by doing well in these aspects can the equipment be reliable. When used in production, bolts should be inspected regularly and loosened phenomena should be handled in time. Only in this way can the stable production process of the machine be guaranteed.

The material from feeding hopper enters into sand making machine, which can be divided into two parts by sub-feeder, one part enters the high-speed rotating impeller from the middle place of impact crusher, and then the impeller can be rapidly accelerated whose speed can reach up to hundreds of times of the gravitational acceleration, and the material must be far away from channel of the impeller in a speed of 60-70m/s. those materials which is being crushed in the cabinet so many times can reach the purpose of fine crushing at last. And those crushed material is discharged from discharging part. In this crushing operation, the material is crushed by each other, which is not connecting with the metal, which can decrease the pollution and then prolong the service life of mining machine.

netflix documentary 'period. end of sentence.' reveals impact of a 'pad machine'
For too many young women around the world, "period shame" the fear that women are impure when they are menstruating prevents them from going to school, praying in public places or other parts of daily life.
In the documentary Period. End of Sentence., women in India tell of the stigma, shame and lack of access to sanitary protection they must confront every month. Co-produced by a former high school student and her teacher, the film took home the prize for best documentary short at the Feb. 24, 2019, Academy Awards.
Many women in India use old cloths for sanitary protection, often reusing them. And an estimated 88 percent of women in India sometimes resort to using ashes, newspapers, dried leaves and husk sand to aid absorption, according to a 2015 study on menstruation myths.
I studied until I reached middle school, but when I started having periods, it became really challenging," says one young woman featured in the documentary. "When I got my period, it was very tough for me to change clothes. I had to go somewhere far off."
Looks and comments she'd get from men made her feel ashamed, and taking time to find secret spots to change became too difficult. She became one of scores of women to drop out of school because of their periods.
In 2006, an Indian engineer named Arunachalam Muruganatham won a national award for designing what's known as "the pad machine," which a few people can manually operate, and using sustainable products, create pads.
The two and a group of other high school students formed The Pad Project, partnering with an nonprofit organization called, Action India. Through bake sales, Kickstarter and yogathons, they raised enough money to purchase a pad machine ($12,000) and produce a documentary.
The Pad Project works to raise money for more pad machines and one years worth of supplies. After that, the profits made from selling pads sustains a microeconomy, employing residents and helping women in the area.
I think when I went there and was face to face with the women and talking to them in detail about their experience and building their relationships with them, it became really clear to me that it was a really big source of shame, said Zehtabchi. "Its held so many of the women back, for so long."
Yenser is now a graduate school at University of Southern California. But for her, the projects impact is just beginning with people reaching out from areas in Pakistan, Rajasthan, Nepal and beyond.
Now that the documentary is on Netflix, I actually get an email about every five minutes from someone in a different country either asking for a pad machine in their village or a village they know of, Yenser said.
